General customs advice is available from our information service for private customers.

You can drop your documents in the post box of our second floor elevator lobby from Monday to Friday, 8 a.m. to 4.15 p.m. We register your documents as having arrived on the day when you deliver them. For a confirmation of receipt, you can call for one of our customs officers to serve you.

When you send documents containing personal details to Customs, we recommend that you use secure email for safety reasons. See the instructions on sending secure email.

Details on Custom’s purchase invoices

Finnish Customs processes and archives its purchase invoices only as electronic invoices. From April 2021 onwards, the Finnish government will only accept electronic invoices that are compliant with the European Standard.

We ask that you send electronic invoices via OpusCapita Solutions Oy (formerly OpusCapita Group Oy), which functions as the state administration’s electronic invoice operator.

Our e-invoice address is:
E-invoice address/EDI ID: 003702454428
The intermediary is OpusCapitaSolutions Oy
Intermediary ID: E204503
Business ID: 0245442-8
VAT ID: FI02454428

Customs checks that the e-invoice corresponds to the order or contract made in writing. Beside mandatory details, the invoice details must also contain the name of the person who ordered the product or service as well as a reference to the order or contract.
